Multilayer structures for magnetic shielding
First Claim
1. A magnetic shield for shielding a microelectronic device from magnetic field effects, the magnetic shield comprising:
- a first magnetic shield; and
a second magnetic shield, wherein the first and second magnetic shields each comprise;
a first layer comprising a magnetic conductive material;
a second layer comprising a non-magnetic conductive material; and
a third layer comprising a non-conductive material, wherein the third layer is interposed between the first layer and the second layer, andwherein the first and second magnetic shields are separated by the microelectronic device.

Abstract
A magnetic shield is presented. The shield may be used to protect a microelectronic device from stray magnetic fields. The shield includes at least two layers. A first layer includes a magnetic material that may be used to block DC magnetic fields. A second layer includes a conductive material that may be used to block AC magnetic fields. Depending on the type of material that the first and second layers include, a third layer may be inserted in between the first and second layers. The third layer may include a non-conductive material that may be used to ensure that separate eddy current regions form in the first and second layers.
